`the extraction of the k.soluble elements from the coee may be varied accordingltothe coarseness of the fragments into which the colte is broken. Another object is to provide a spreader "between the ground coffee holder and the water which falls upon the coffee and percolates through it. Another object is to 'provide a perforated separation and spreader disk above the ground coffee to lkeep the ground coffee in a concentrated condition. Other objects pertain to Vthe construction of the holder for the container of the brew and to the construction of the handle for the holder and the common cover for the percolator and the said container.

Referring to the accompanying drawings, Fig. 1 is a side elevation of my improved percolator; Fig. 2, a central vertical section of Fig. 1, the section being through the pouring spout or lipand the handle'bein shown in side elevation; Fig. 3, an enlarge central vertical section ofV the container for 'the ground cofee and of the spreader separation'disk, the filter paper, and one of thel de vices fordetermining the time for the water to percolate through the colee;,Fig. 4, a f

plan view of Fig. 3 on a reduced scale with the removable parts -thereof omitted; Fig. 5, a plan view of the lspreader or separation disk; Fig. .6, a plan of one of said time determining devices; Fig. 7, a Vplan view of the filtering disk orf medium; and Fig. 8, a plany of the holder. v

- On the drawings, 1 show a holder or frame comprising the crossed metal strips or members 1 and 2 and the circular metal ring or Y* member 3; The member 1 has a transverse `depressed portion V4: to receive the crossing ymember 2, so that the upper surfaces of the ,members l and .2 may be Hush, 0r at the Specication of Letters Patent.

same'v level. A rivet 5in the crossing portion of the members 1 and 2y holds them rigidly together. kThe member 1 extends out hori- Y zontally at equal distances from the rivet 5 and then curves, downwardly tov form the inner leg members 6 and then backwardly on the outer faceofthe members 6to form the outer leg members 7 Q That end of the 'member 1 which is opposite the `place where the handle 8 is to be seated extends up'vertically from the'leg member 7 to the'gring 3, to which it is connected by the rivet 9. end of the member 1 is marked 10.`

Y `The upper member of the loop extends upwardlyatv its outer end somewhat above the inner end as shown at 18. K The member 2 extends laterally, in'bot'n ydirections vfrom the vrivet 5 the same distance that the member 1 extends laterally from the rivet. The member 2Yhas leg memlbers '6a and 7a preferably constructed 'like vthe leg members 6 and 7, and has above the latter members the vertical endmembers 10 connected by the rivets 9a to thering 3.

The preferably glass container 19, which i is also a serving or pouring vessel, has its l bottom 20 seated on the base or crossed portions ofthe frame'members 1 and 2 and its circular side vwall standing in the ring 3V with its upper edge 21 somewhat vabove the ring 3. The container has in thev edge 21 curing lip 22 arrangedV opposite the han e 8. y

23'is a'fpreferably nickel-plated copper percolating vessel having its upper portion in the shape of a hollow'- spheroid with its lower side restingon the edge 21 ofthe oontainer 19. The upper side of the vessel is horizontal and has the @B11111524 with lthe cover 25. The lower side of the spheroidal portion of the vessel 23 has the downward extension 26 terminating in the circular edge 27. 28is a cup-like container for the ground coffee. VIt has the horizontal perforated circular bottom 29 and the an-V nular horizontal shoulder 30 near its upper edge.v The upper end of the container 28 telescopes over-theend 27.` Whilethe parts 27 and 28 may be prevented from laccidental disengagement vlby various means, .I v.find that yif they .have a lclose `fit, the friction between vthem forms a satisfactory securing,r means. 31 is a disk of filter medium, as paper, resting on the upper face of the lbottom .29, and'v 32 is a circular gage ring fitting ,ther container 28 and lyingv on the filter p y:iper-.31. It lhasthe-upstanding stiffening an e 33 in engagement'with the'inner face of t econtainer. The perforated spreader disk'34-is held betweenthe shoulder 30 and ythegedge .27. It is provided with the knob 3,5:by which it can beremoved or replaced.

The partsbeing-asshown in Fig. 2, and .ground coffee being in the container'28 between the filter paper 31 and the spreader 34, .the required amount of'water is'poured into-the vessel 23 through the opening 24. The water passes first through the spreader,

...by which the water-.is evenlyspread or dis- .tributed `tor-the ,ground coffee. The water is thus caused lto percolatey evenly throughout the coffee. The water ycharged with the .soluble matter in the coffee, that is, the brew, passesthrough a filter paper 31 and theper- ,-forations in thebottom29 and collects in the container,- or pouring vessel 19. If desired .the liquor inthe lvessel 19 maybe passed through the ycoffeeagain. The vessel 23 with .its'pendent parts is.removed and the cover 25 may be placed on the vessel 19 with .rthe'u'pwardly Vcurved tongue 36 in the slot 17. his tongue servesto prevent the cover `from sliding on the vessel 19, particularly V,When the klatter is-tilted'to pour out coffee .through vthelip 22. Several gagefrings may lbe provided, each covering a .different percentage ofthe area'of the filter 31 or the perforated .portion ofthe bottom 29. When .coarse `coffee is used lthe gage ring cover- .ing more of the filter 31 orbottom 29 is used than .when-thecoffeecis ground fine- The proper VK ii`.slrfor the size of the broken yfrag- ;ments ofthe 'coffee will be selected so-as 'to ,lgrve -thedesiredf strength of the brew.
